BUILDER MOTION-F93 WINDING MACHINES.

Application filed March 12, 1923. Serial No 624,464.

To all 1071 01m it maxy comer n:

Be it known that 1, JOHN LiNnsAY, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented a Builder Motionfor finding ltflachines, of which the following is a specification.

This invention relates to yarn winding machines, and more particularlyto builder motions for such machines, the object of the invention beingto provide a builder motion which ceases to operate automatically uponthe breaking of the yarn, the invention further residing in theprovision of the novel and improving features hereinafter fully setforth.

In the attached drawings:

Figure 1, is a transverse fragmentary section of a portion of a windingmachine;

Fig. 2, is a plan view'of that portion of the winding machine shown inFig. 1;

Fig. 3', is a vertical section on the line 3-3, Fig. 2;

Fig. 4, is a section on the line 44, Fig. 3, and

Fig. 5, is a section on the line 55, Fig. 2.

VVith reference to the drawings, 1 designates one end of the main frameof a winding machine which supports a table 2, upon each end ofwhich ismounted a standard 3. Extending between these standards 3 the presentinstance, a pair of tubular rods 4,4, which support bracket arms 5,which carry the reels 6' from which theyarnis fed to the spools. Thespools 7 are each carried by a vertical shaft 8 mounted in suitablebearings in the main frame and having thereon a grooved pulley 9 whichis connectejdby means of a belt 10 with a pulley wheel 11 on the maindrive shaft 12, the latterbeing connected with 'a suitable source ofpower (not shown). The shaft 12 also carries a pinion 13 which mesheswith a gear wheel 14 on a shaft 15 mountedin the frame, this shaft alsocarrying a pinionl6 which meshes with a gear 17 on a'cam shaft 18. Theshaft 18 carries at each end of the frame of the machine a cam 19 whichin each instance is engaged by a cam roller 20 on a frame 21 which isvertically reciprocable in the main frame of the machine. The frame7211s, in the present instance, counterbalanced at each end by a'we'ight22- connected is, in.

with the frame by a chain 23 which passes over a suitable roller 24' ona short shaft 25 secured in the main frame.

The frame 21 carries at each end a vertical rod 26 which is slidabl'e inguides 27, 27, on the main frame, the rods 26 supporting'at their upperends a cross bar 28, upon which are mounted the builder motions for'thevarious spools.

The separate builder motions'compiise a bracket 29which is secured tothe cross bar 28, and which has therein a bearing 30 for a vertical,threaded shaft 31,,a collar 32secured to the shaft 31 maintaining the.shaft in the bearing 30, A second collar 33 is secured to the bottom ofthe shaft, and'interposed between this collar 33 and the bearing 30 isa'horizontal arm 34'which is loosely mounted on the vertical shaft andwhich carries a pawl 35 naintained by means of a spring 36 in contactwith the teeth of a ratchet wheel 37, which is fixed to the said shaft31 and which lies between the arm 34 and the bearing'tO. p 7

' A coiled spring 38 is secured to the arm 34 and to a pin 39 on thebracket 29, said spring tending to maintain the arm 34 in apredetermined position and returning it to this position when the arm isoscillated on the shaft in a manner to be described hereinafter. Aspring detent 40 upon the bracket 29 bears against the ratchet 37 "andacts as a damper preventing returnmotion of the ratchet and any motionbeyond that given by the pawl 35 I g Adapted to travel on the threadedportion of the vertical shaft 31 is a carriage consisting of a ratchetwheel41 having a down-- wardly extending hub 42,to which secured in suchmanner as to permit free rotation of the hub therein an arm 43, said'armhav ing a rearward extension '44 through "which extends a verticalrod'45 which is fixed in an arm 46 off the bracket 29, this rodconstituting a guide for the carriage and preventing rotationalmovementaround' the shaft31 of the arm 43. At the forward end of the arm43 is a receptacle 47 which carries at each end a porcelain guideelement 48', 48, and felt pads 49,49, the purpose of which will bedescribedhereinafter.

The receptacle end ofthe 'arm 43 also cartil ries at the top andpivotally secured to a lug thereon a detent 51 which is adapted toengage the teeth of the ratchet 4:1 and which carries a wire rod 52which extends in a substantially horizontal position over the centerportion of the receptacle d7. A suitable recess 53 is provided in theouter wall of the receptacle 1? to permit down ward movement of the arm52 sufficient to carry the detent 51 clear of the ratchet 11.

Pivot-ally secured to the top of the ratchet 41 by means in the presentinstance of a screw 54; is an arm 55 which is threaded at its centerportion to correspond with the threaded portion of the shaft 31, and thearm 55 is retained in an advanced position with the threads thereof inengagement with the threads of the shaft 31 by means of a sprin 5o whichis confined between the back of the arm 55 and a lug 57 on the saidratchet wheel. A pin 58 on the ratchet wheel limits the forward movementof the arm 55 towards the shaft 31.

Secured to the rear side of the receptacle portion 4:7 of the arm 43,one at each end thereof, is a porcelain guide 59 and (50 1e spectirelywhich extend upwardly and over the opposite ends of the receptacle.

The operation of the device is as follows:

The yarn is wound from the reel 6 onto the spool 7 in the usual manner,the latter being rotated from the main shaft 12 through the belt 10 and.the pulleys 11 and 9. The yarn in passing from the reel to the spools isled downwardly and under the guide 60, across the top of the receptacle,and under the guide 59, the guide 60 being hooked at the ends to preventlateral displacement therefrom of the yarn. Between the guides 59 and 60the yarn passes under the arm 52 of the detent 51, the normal tautnessof the yarn being sufficient to maintain the detent in engagement withthe ratchet wheel ll. he felt pads 4E9, 419, in the receptacle 47 may beoiled for the purpose of oiling the yarn as it passes thereover.

During the normal operation of the machine, the frame 21 is reciprocatedvertically in the main frame of the machine by the cams 19, suchreciprocation being transmitted to the builder motion through the rods26. At each downward movement of "the builder motion, the arm Set isbrought into engage ment with a cam 61 adjustably mounted on the table2, this cam forcing the arm in the direction of the arrow, Fig. 1-,against the tension of the spring 38, and through the pawl 35 turningthe ratchet ST through a predetermined angle. Movement of the ratchet 37carries with it the shaft 31, and through the threaded arm 55 efiects amovement of the carriage 4143 upwardly on the shaft. In this manner,while the entire builder motion is reciprocated opposite the spool 7 therider is gradually fed upwardly 011 the shaft 31, with the result thatthe yarn is built up evenly upon the spool 7 after the well knownmanner.

In the event of the yarn breaking, the arm 52 of the detent 51, whichnormally is supported by the yarn, will drop downwardly and retract thedetent 51 from the ratchet all, thereby permitting rotation of theratchet 41 with respect to the arm 13. As a result of this free rotationof the ratchet 41, the upward feeding of the carriage on the shaft willbe interrupted, the ratchet 4E1 merely turning with the shaft 31 as thelatter is actuated by the cam 61. By reason of this interruption of thebuilding action upon the breaking of the yarn, the operator is permittedto mend the break and restart the winding operation at the exact pointthat it was left off, the evenness of the winding on the spools thusbeing preserved.
